Title: Improvements in or relating to wireless receivers and cabinets therefor
IPC: H04B1/08
Filed: 1958-09-02
Abstract: 900,214. Radio receiving apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 2, 1958 [Sept. 5, 1957], No. 28164/58. Class 40 (5). A radio receiver cabinet in which the upper and side walls are formed by an envelope of plywood, having at least two bends, is characterized in that at least a portion of the edge of the rear wall lies in grooves on the inner side of the rear edge of the upper and side walls. The rear of the chassis of the receiver is supported by the side walls of the cabinet by means of a supporting member which allows displacement of the walls outwards. The top and side walls of the cabinet are formed from a strip of plywood 1 which is bent twice, approximately at rightangles. A groove 3 adjacent the front edge extends substantially the length of the strip and houses a panel 5 of synthetic resin which forms the front panel. On the rear side of the panel 5 is formed projections 7 and a ledge 9. The ends of the ledge are secured to the side walls by screw 27 which passes through U- shaped brackets 25. The front of the chassis is secured to the projections 7 and the rear of it is supported by U-shaped brackets 19 which fit into tongues 15. The brackets 19 are surrounded by small bands of dielectric material 23 and clamped lightly in the recesses 17 allowing outward displacement of the side walls. The back wall and bottom, which may be integrally constructed, are held in place by tongues which fit into grooves 37 and 41 and by clips 45, and may be inserted or removed by flexing the side walls. Alternatively the grooves 41 may be replaced by grooves 49 along the lower edge of the side walls.

Title: Improvements in pressure-controlling valves
IPC: G05D16/10
Filed: 1932-10-10
Abstract: 407,429. Pressure-regulating valves. BELLISS & MORCOM, Ltd., Ledsam Street Works, and WARD, C. F., 146, Wentworth Road, Harborne, both in Birmingham. Oct. 10, 1932, No. 28168. [Class 135.] A valve device, more particularly for charging gas-bottles, comprises a valve c closing in the direction of flow of the gas and mechanically held open by a valve f closing a passage q under the pressure of a spring-pressed piston g of larger area than the valve f. As shown, compressed gas passes from the inlet a through the reducing valve c to a gas-bottle attached at b. The valve c is held off its seat by a stem h connected to the ball valve f, which is pressed on to its seat by the piston g under the action of a spring g<1>. When the pressure in the outlet b has risen to the desired value, the valve f is opened, and is held open by the outlet pressure acting on the piston g. The valve c is thus allowed to close, and is held closed by the inlet pressure when the gas-bottle is removed. To re-open the valve c when a fresh bottle is attached at b, the pressure above the valve c is relieved by opening a needle-valve i, or a stopcock. If the outlet pressure rises too high owing to failure of the valve c to seat properly, the safety-valve j is opened. A non-return valve mav be inserted in the outlet b. The valves may have renewable stainless steel seatings.

An air heater comprises a cross-flow fan 2 which draws air through an inlet 14 of a casing 1 and discharges it over an electric heating element 36 through an outlet 15. Walls 3, 4 guide the air through the fan and allow a flow over a thermostat 41 controlling the heater. In an embodiment (Fig. 6), two rotors are used for the fan which draws air through inlet slits 121a and passes it over a heater 128 to the outlet 118. A nozzle 131 may be fitted as shown over the outlet. The rotor, motor and heater may be formed as a unit as described in Specification 943,398. In further embodiments two electrical heaters extend at an angle to the flow of air from the fan whereby maximum heating occurs where there is maximum flow of air. Specifications 876,611 and 943,767 also are referred to.

[Also in Group XXVII] The duration of opening of electromagnetically operated fuel injection valves 19 is controlled by varying in accordance with engine Operating conditions the voltage applied to a primary coil 12 coupled by a core 14 to a secondary coil 16 which energizes the valveoperating solenoids. A voltage E is connected through potentiometers R 1  ... R 4  to the centre tapping of the coil 12, the opposite ends of which are connected to alternate segments 26 of a rotary switch having an earthed wiper arm 24 rotating as a function of engine speed, which arm connects the opposite ends of the coil to earth in succession so that the current flows alternately in opposite directions through the two halves 12a, 12b of coil 12. The time taken for the flux in core 14 to change from positive to negative saturation, and hence the time duration of the current induced in coil 16, is controlled by the voltage applied to coil 12 and is varied by adjustment of the potentiometers R 1  ... R 4  in accordance with engine variables such as ambient temperature and pressure, engine temperature, induction pipe pressure, and exhaust temperature and pressure. The valve solenoids are connected to corresponding contacts 20a ... 20h which are connected to earth by the arm 24 in succession, in accordance with the cylinder firing order, at the times when a current is induced in the coil 16, thereby completing the circuit of the appropriate injector valve which is opened for a period controlled by the potentiometers R 1  ...

The dyes are made by reacting a trihalo-triazine with appropriate aminoazo dyes and ammonia or the required amine corresponding to Y.  The reaction may be effected in any sequence and intermediates may be isolated before further reaction.  Preferred dyes are those where n is 1, R is a disulphonaphthyl residue and A contains an acylamino group of up to 4 C atoms #s to N2.  R1 is indicated as a phenyl group which may have methyl or alkoxy substituents, or a naphthalene residue.  Preferably the dyes contain more than one COOH or SO3H group per azo group. Chlorine is the preferred halogen in the halo-triazines.  R is indicated as a benzene, naphthalene, pyrene or chrysene residue. Representative of amines for specified values for Y are methyl-, diethyl-, isobutyl-, cyclohexyl, b -chlorethyl- and g -methoxypropyl-amines, ethanolamines, toluene sulphonic acid amide, glycocol, ethyl aminocarbonate, amino acetic acid ethyl ester, aminoacetamide, morpholine and especially aniline-2, 5-disulphonic acid, aminonaphthalene mono- or disulphonic acids, 1-aminodiphenyl-41-sulphonic acid and N-methylamino ethane sulphonic acid.  Amines containing water-solubilizing groups are used only when dyes are chosen which contain a single SO3H or COOH group.
